A Specification of Letters Patent. Patented March 10, 190B. giiialapplication filed A ri 1 ,1907, Serial No. 368,568. Divided and thisapplication filed September 24, It I 1 1907. SerialNo. 394,309.

- interior of the druml, to allow the fire extinguishing fluid to-passout of the drum 1 .through the valve L when opened and into the hose Lto the nozzle thereof to extinguis h a fire. .Normally'the valve L isclosed and the hose L is woun'don the drum I, and the entire chemicaltank I is supported on therear end of the vehicle, and for this purposethe following arrangement is made: The blocks K previously mentionedfitinto 0 en bearings N 'held on swing arms N exten 'ng longitudinallyand fulcrumed at N .to the vehicle body, and the said swing arms N areconnected with ropes-or cables 0 extending upwardly and winding on adrum .0 journaled in suitable bearings on the vehicle A.

.The ends of the drum 0 are provided with handles or'crank arms 0 underthe control of the fireman, to allow llllGfiI'lTlS N to swing downwarduntil the stand J rests on the ground, the bearings N then being openatthe rear, so that when the vehicle A is drawn forward the blocks K mo eout of the bearings N, and thechemical tank I remains standing on theground while the vehicle A moves forward. In. a like manner when thevehicleis backed u the bearings N engage the blocks K, and tiien by theoperator turning the-crank arms 0 the ropes or cables 0 are wound up onthe drum O, to impart an u ward swinging motion to the swing arms N witha view to lift the tank I off the ground and to-hold it-supported fromthe rear-end of the vehicle, as plainly indicatedin Figs. land .2. 'Whenthe swing arms N reach a horizontal position against the underside ofthe'vehicle body, then the free ends of the said swing arms are engagedby catches P, to lock theswing arms in a raised' position. The catches Pare fulcrumed on the vehicle body and are pressed on by springs P so asto hold thecatches in engagement with the swing arms N. The upper endsof the catches P are ivotally connected by links P with arms I held on atransversely extending shaft P journaled in suitable bearings arrangedon the vehicle body, and on the said shaft P are arranged handles Padapted to be taken hold of by a fireman, to move the same forward, witha view to disengage the catches P from the swing arms N immediatelyrevious to lowering the chemical tank as before explained. Stops Q heldon the rear end of the vehicle project close to therear faces of theblocks K, so as to hold the same in the bearings N and thus preventaccidental disengagement of the chemical tank I from its support on therear end of the motor vehicle.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent:

1. In a fire-fighting apparatus, the combi- I nation with a wheeledvehicle, of a chemical vehicle, a chemica tank, and a su port for thesame com rising arms mounte to swing on the vehic e and arranged tonormally hold the said tank above the ground, the said swing arms beingcapable of releasing the said tank and delivermg it to the ground.

2. A fire-fightin apparatus comprising a l tank, a support for the same,the said support having swing arms for supporting the chemical tank andfulcrumed on the said vehicle, and a locking device for locking the saidswing arms normallyin a raised position.

3. A fire-fightin apparatus comprising a vehicle, a chemica tank, asupport for the same, the said support having swing arms for suppprtingthe chemical tank and fulcrumed on the said vehicle, a locking devicefor locking the said swing arms normally ina raised position, andmanually controlled means arranged on the vehicle and connected with thesaid swing arms, to sw .g the latter down or up. 4. A fire-fightingapparatus comprising a vehicle, a chemical tank, a support for the same,the said support having swing arms for supporting the c emical tank andfulcrmned on the said, ehicle, and a stop on the vehicle for holding thechemical tank against accidental displacement on the said swing arms.

5. A fire-fighting apparatus comprising a vehicle, a chemical tank, asupport for the same, the said support having swing arms for supportingthe chemical tank and fulcrumed on the said vehicle, a manuallycontrolled drum mounted on the vehicle, and cables winding on the saiddrum and connected with the said swing arms;

6. A fire-fighting apparatus. comprising a vehicle, and a chemical tankremovably connected with the said vehicle, the said tank being in theform of a drum, 0; stand on which the said drum is mounted to turn, and

a hose adapted to wind on the said drum and connected at one end withthe said drum.

7. A fire-fighting a paratus comprising a vehicle, and a chemica tankremovablv connected with the said vehicle, the said tank bein in. theform of a drum, a stand on whic the said drum is mounted to turn, a hoseada ted to wind on the said drum and connects at one end with the saiddrum,

and a valve at the connection of the said hose with the said drum. 8. Ina fire-fighting apparatus, a vehicle, a

tank, bearing blocks supported at the ends of the tank, and arms mountedto swing on a the vehicle and having open bearings for engaging the saidbearing blocks, to support the tank.

9. A fire-fighting apparatus comprising a vehicle, a tank in the form ofa drum, a

stand, the shaft of the drum being journaled I in said stand, bearingblocks held on the said shaft, and arms for supporting the tank andstand, the said arms being f'ulcrumed on the vehicle body to swing upand down and having open bearings for engaging the said hearing b ocks.

10. A fire-fi hting apparatus comprising a vehicle, a tan for containinga fire extinguishing fluid, arms for sup orting the tank at the rear endof the vehic e, the said arms being fulcrumed on the vehicle to swing upand down and provided at their free or rear ends with open bearings, thesaid tank being provided with hearing blocks for engagement by the saidopen bearings of the arms, manually controlled means connected with thearms for raising the same to lift the tank catches for locking said armsin the raised position, and means for preventing accidentaldisengagement of the bearing blocks from the said open bearin s of thearms.
